717 * Reset the chip. Useful if a hang is detected. Returns zero on successful

719 *
720 * Procedure is fairly simple:
721 * - reset the chip using the reset reg
722 * - re-init context state
723 * - re-init hardware status page
724 * - re-init ring buffer
725 * - re-init interrupt state
726 * - re-init display
